Background of the invention A device used to fix a toner image on a recording medium surface includes a pressure roller and a heating roller. The first figure shows the structure of a conventional holder. The heating roller includes a roller body 10 with a halogen lamp 12 inside; the pressure roller includes a roller body 16 with an elastic layer 14 ° on the outside and a recording medium 18 as paper. Or a slide, which carries toner 20, and after heating and rolling by a holder, the toner image is fixed on the surface of the recording medium 18. This device has disadvantages. Since the heat source halogen lamp 12 transmits thermal energy to the roller body 10 through radiation, there is a considerable heat loss. This heat loss mainly comes from the radiation absorption loss of air and the loss of hot air. With this structure, the efficiency of the heat source is difficult to reach more than 70%, so the power loss cannot be reduced. Printed by i-In Hi HI I --- I--1.
